I like this - it is pretty much permanently attached to my Leica TL.On this crop body it is a 16mm equivalent lens and as it is so wide, there is little or no need for focussing.This makes it incredibly compact and pocketable.Quality is better than you might expect, it has a bit of a purple tinge, but that is character.For the price, this is great fun and nice to use.

TBH I never really tested this out photographically owing to 2 major issues. One, the focussing ring is so stiff, turning it, is not easy and would be a PITA if I had to use it. Secondly, there are no markings on the focusing ring so there is no indication where the focus is by looking. Could be anywhere between close up to infinity which is on the focussing ring a lot of movement. if it was marked you could at least glance at it to know where you are starting from.Returned for a refund.

Advertised for Nikon Z but it’s aps-c so doesn’t work with the majority of Nikon Z cameras without a li tied image and vignettes
